Accumulated QPF in GRIB files?

Youngling Posts: 67 Join Date: 11/2/12 Recent Posts

I was looking at some recent heavy rainfall events in east TX and western LA, and so was comparing sources of QPF. I noticed the WSUP viewer displays run-accumulated QPF, but I didn't see it in the GRIB files on AWS. Do you compute the run-accumulated QPF on the fly, or might there be accumulated QPF data within the GRIB at certain projections?

Didn't see the Run Accum listed in here: https://docs.google.com/spreadsheets/d/1ikACiJsL4cz3pW3_l4lHvvI40iKmviJ0bLAi4NkPFV8/edit#gid=0

Might the Run-Accum be added in a future set of output data, as model output contains that?

Hey Jack,

You're correct that Total QPF is not produced by the NBM natively. We accumulate the deterministic QPF06 values to create the Total QPF grids.

Adding it to the NBM output is a question for the NBM group.
